Which electrocoagulation system should you to purchase?

Electrocoagulation has evolved considerably since Dietrich’s patent in 1906. Electrocoagulation is the process of passing electric current through a liquid. The method and chamber configuration greatly affects the energy efficiency and longevity of the system. Please consider the following when deciding to purchase a system.

Water Flow

Electrocoagulation creates hydrogen and gas bubbles. The bubbles float vertically. In chambers that have a water flow other than vertically the bubble collect next to the horizontal surface or corners causing the pressure to build up in the chamber, and creating an insulating factor which stops the current from passing through the water. Powell Water Systems, Inc. engineers the system so the bubbles float in the same direction as the water flow.

Residence Time

Electrocoagulation moves the electrons through the water between positive and negative plates. This causes a surface charge on the plates. Positive and negative partials attach to the plate surface magnetically. When the polarity is reversed the magnetically attached particles are repelled into the water flow. The electron flow stops and reversed direction when the polarity is reversed. The chamber must have sufficient residence time or volume to allow the water to be treated even though the power is off for 1/30 of a second during polarity reversing. Powell Water Systems, Inc. designs the system for a one-minute resonance time in the chamber.

Voltage

Electrocoagulation depends upon the amount of amperage passing through the water. Electricity is purchase as power, which is volts times’ amp.The amount of voltage required to make the metal leave the metal blade is about 1.5 volts DC. The voltage above 1.5 Volts simply creates heat in the liquid, consumes more energy, and dissolves the metal blades faster. For example if a liquid requires 1 amp per gallon to complete the reaction please consider the following energy difference. If the system operates at 3 volts per gap and 1 amp the energy consumed is 3 watts of electricity per gallon treated. If the system operates at 30 volts per gap and 1 amp the energy consumed is 30 watts of electricity per gallon. If the system operates at 80 volts per gap and 1 amp the energy consumed is 80 watts per gallon. In other words the lower the voltage per gap the less energy is consumed per gallon of water treated. Powell Water Systems, Inc. engineers the system to operate at 3 DC volts per gap.

Surface Area

Electrocoagulation is a surface reaction. When considering which electrocoagulation chamber to purchase, determine the surface area within the chamber per gpm. Powell Water Systems, Inc. engineers for 3,480 square inches per gpm.

Amperage

Electrocoagulation systems require amperage to treat the water. The amount of amperage draw is dependent upon the conductivity of the water. If the water is not conductive then no amperage will be used. The system should be designed with adequate wiring and electrical capacity to deliver adequate amperage if needed by a particular water stream. Powell Water Systems, Inc. engineers for 0.375 amps per square inch or 130 amps per gpm.

Authorization

The electrocoagulation industry is full imposters, fraud, and deception. One-way to be sure that you’re purchasing a legal or authorized system is to check patents. A patent is a grant from the government to make, use, or sell. It is illegal to make, use, or sell an item covered by current patents with out the owner’s permission. Powell Water Systems, Inc. utilized patents and patents pending in the United States Patent 6,488,835 issued December 3, 2002 and # 6,139,710 issued October 31, 2000 and many nations around the world. To verify patents go to http://pctgazette.wipo.int/ and search under the international application number PCT/US99/04312, filling date 26 February 1999 (26.02.99), international publication number WO 99/43617, international publication date 2 September 1999 (02.09.99), inventor Powell, Scott, Wade.
